Column efficiency of new VST was then studied with ethanol-water system and was compared with that of sievetray.
在此基础上,又用乙醇-水系统在常压下测定了该塔的塔板效率并与筛板塔进行了对比。

The high efficient flow guided sievetray and packing are adopted in the innovation of vinyl acetate Methanol methyl acetate distillation column.
采用高效导向筛板与填料对乙酸乙烯-乙酸甲酯精馏塔进行了技改设计。
